No, Manga wouldn't have to get permission.
Being the distributor, they can distribute to whomever they please as long as the company they distribute to can legally sell retail products.
Well I understand that but I'm just curious if BW would get pissed and pull the Macross Plus license from Manga. Japanese companies have pulled the US liscense before from US companies. Most recently, Toei pulling Sailor Moon from ADV.
why woudl they.
